IMPROVEMENT IN cAR-AXLE BoxEs.

Specification forming part of Letters Patent No. 193,593, dated July 31,1877 application filed May 26, 1877.

To all whom it may concern Be it known that I, TuoMAs A. BissELL, ofDetroit, in the county of Wayne and State of Michigan, have inventedcertain new and useful Improvements in Car-Axle Boxes, ot'y which thefollowing is a specification:

The first part of my invention relates to an improvement in theaxle-box, whereby all the oil passing back onto the axle-collar isreturned to the oilcellar,instead of passing back and out of the box,and which also secures a greater depth of' oil in the cellar. Itconsists in a pocket or diaphragm in the box, under, and extendingnearly up to, the axle, and in combination therewith a wooden leaderstraddling the collar and pocket, to conduct the drips to the oil-cellaragain.

The second part of my invention relates to the shoe for incasing orholding the journalbrass, so constructed as to receive and secure abrass stop bar or plate, which limits the end play of the axle, andthereby relieves the back end of the axle-brass from collari'riction.Either brass can be renewed or replaced when worn without renewing theother.

Figure 1 is a longitudinal vertical section at :v w in Fig. 2, which isa crossvsectiou at y y in Fig. 1, looking toward the front. Fig. 3 is asectional plan at z z. Fig. 4 is a perspective view of the shoe andstop-plate with the brass removed.

In the drawing, A represents the axle, having the usual journal A andcollar a. `B is the box, provided with the usual packing C, to excludedust. In front of the packing-slot another one is cored in the top ofthe box, in which is inserted a wooden plate, D, hollowed out on thelower end to ride the axle-collar, and take up the oil running onto it,and which drips off from its ends b b, at the sides of the box, into theoil-cavity of the box on the outside of a pocket, E, cast in the bottomof the back end of the box. The front wall or diaphragm of this boxextends close up to the journal of' the axle, which thereby increasesthe capacity of the oil-cellar, and at the same time any dirt or dustcoming into the back of the box through the packing is caught in 'thepocket, and prevented from mingling with the oil to abrade the journaland brass.

F is a light brass, which, in the present case, is cast with a lug, c,at the front end, andis held or incased in an iron shoe, G, cast with apendent flange, G', at the front end, strengthened by webs at the sides,forming extension of the side flanges. An inclined eye is cored in theflange G', which receives a lug, d, east on the back of alight brassstopplate, H, against which the end of the axle comes, and whichprevents end play in the latter. A socket is cast in the top of theplate H, to receive the lug c of the journalbrass, and thereby keeps theplate H from moving.

At each side of the box, in front of the pocket, there is cast aprojecting guard-wing, e,`to prevent the waste from being pushed aroundthe pocket in packing the box, and

.thereby insuring a free flow of oil from the sides of the pocket to thebody of thecellar. What I claim as my invention is- 1. In an axle-boxhaving the usual dustexcluding packing C, the combination of theoil-pocket E, extending close to the journal, and the forked plate'D,adapted to ride loosely on the axle-collar a, and return its drip to theoil-cellar, constructed and arranged substantially as described andshown.

2. The shoe G, cast with a pendent flange, G', at its front end, adaptedto receive and secure the stop-plate H, substantially as and for thepurpose set forth.
